【McQueen Trial】 Main components of McQueen [Copy link]

 

 

Because DFRobot did not provide much information about McQueen, I simply analyzed the main components. The front and back of McQueen There are not many components on the board, the main ones are as follows:

Next to the ultrasonic sensor is the PS3120A capacitor boost chip. The chip next to the power socket, the model number is not found. Behind the infrared sensor is the LM358 op amp. Between the two motors is the single-channel motor driver IC YX-75V18. This content was originally created by EEWORLD forum user dcexpert.

Isn't there a wiki? There should be more detailed information there? There is a link on the event page

Can you contact the manufacturer to provide more detailed information?

Yes. What information do you want, and what aspect?

For example, schematics or something

Will the schematics be provided? I think it's difficult.

I asked the administrator and he said it can't be provided.

Most of the functions are fine without the schematic diagram, only the I2C chip model is not found, it seems to be a chip with I2C to PWM function.

Thank you too. I also want to know what main components are used on McQueen. Your post should be the only one that shows all the components. I just searched it out today with the help of your picture.
